CONDUCTOR SUPPORT AND INSULATOR.

SPECIFICATION forming part of Letters Patent No. 503,039, dated August 8, 1893. Application filed I'ebruary 1, 1893- Serial No. 460,611. (No model.)

To all whom it may concern.-.

Be it known that I, WILLIAM B. EssIoK, a citizen of the United States, residing at Man ley, in the county of Cass and State ofv Nebraska, have invented a new and useful Improvement in- Insulators and Supports for Underground Trolley-Wires, which improvement is fully set forth in the following specification and accompanying drawings, in

Which- Figure I is a perspective view of the interior of an underground conduitshowing a trolley wire provided with my improved insulator and support; Fig. II, adetail, partly in section, showing the application of the invention; Fig. III, a transverse view, and Fig. IV, a modified form of the insulator and support.

My invention relates to improvements in apparatus used in conjunction with the trolley system of electric motors for railway and street cars, and its object is to obviate the numerous and valid objections to the prevailing method of suspending the conducting wires overhead, and to provide means whereby they may be easily and effectively insulated and supported in underground conduits.

The peculiar features of my device will be readily understood by reference to the accompanying drawings in which 2 designates a section of an underground tunnel or conduit and 3 a beam suitably fixed in the bottom thereof. The beam may be made of wood properly prepared for the purpose. The insulator and supporteis made of glass or other suitable non-conducting material, and is insorted in the beam or otherwise attached thereto. A shallow groove or channel 5 in the top of the insulator. forms a seat for the conducting Wire 6 which is held securely in its place by a stay or brace 7 extending through an orifice 8 in the body of the insulator and directly beneath the conducting wire. The ends of the stay are suitably attached to shoes 9 which are. soldered or otherwise fastened to the conducting wire.

If a stronger support be desired, a cast metal saddle 10 may be fitted to the top of the insulator as shown in Fig. IV. If there should be curves in the line, it is only necessary to increase the number of insulators to the extent required for the purpose.

' It will be understood that I do not confine myself to the form of the device as shown in the drawings, it being obvious that a variety of forms may be adopted without departing -from the principle involved in the invention.

wire and a brace passed through said opening and connecting with said shoes, substantially as specified.

In testimony that I claim the foregoingI have hereunto set my hand in the presence of witnesses.

WILLIAM B. ESSIOK.
